Rob Kardashian has been gaining weight like crazy these past few months and nobody is quite sure why. However, after these new pics went viral, we’re starting to gain a better idea of why the KUWTK star is packing them on so fast.

According to sources, Rob has been sipping lean and puffing that ganja like crazy (those munchies will get you.) It’s apparently getting so bad that his family wants him to go to rehab for his addiction problem. They’ve even been contacting different rehab facilities but rob is refusing the help. Let’s hope he stops the madness and goes to rehab so he can shed those pounds and look normal again! Check out the pics in the gallery of Rob and his cup full of lean.
